Stone Age

About two and a half million years ago,before man earnt the use of metals,man used stone as raw material for making tools and weapons.This period was called stone age.The stone age can be divided into three parts that is Paleolithic or old stone age,Mesolithic or middle stone age,Neolithic or new stone age.During the Paleolithic age which lasted for about 10,000 years ago,the peaple learned how to use stones for cutting and chipping.They used to sharpen pieces of rocks into a tool for cutting.As a result of this they devloped the first knives,spear heads and scrapers.As the time went by they learnt how to use small chips of stones for making arrow heads and other finer powerful tool.
The next period was mesolithic period when people knew how to make smooth and finely finished tool including farming tools and weapons like the axe head out of stone.This period lasted for 9,000years.
The next period that was neolithic came after the ice age.People hunted smaller animals and fishes for survival.It was only in the neolithic period when the farming tools were devloped that these people gave up their nomadic life and settled in villages that we now call villages.
